isualizing RF Interference: Spectrum analyzers display radio frequencies across a range, showing signal strength and potential interference sources. This is crucial for identifying non-Wi-Fi devices that might be disrupting your wireless solution.

ASK (Amplitude Shift Keying): Digital data is represented by changes in the amplitude (strength) of a carrier wave.
FSK (Frequency Shift Keying): Digital data is represented by changes in the frequency of a carrier wave.

Incorrect session keys prevent devices from successfully joining or sending valid encrypted frames. High SF actually improves range; LoRaWAN does not operate on 5 GHz.

HTTP's Popularity: HTTP is the foundation of the web, making it widely known and supported.
Developers have extensive familiarity with its concepts (methods, headers, status codes, etc.).
REST APIs and Webhooks: These often leverage HTTP for communication, building upon existing knowledge and tools.
Tradeoffs:
Security: HTTP itself is not inherently secure; HTTPS or additional layers address this.
Speed: Protocols optimized for IoT may have lower overhead, but HTTP's simplicity often outweighs minor performance differences.

Importance of Time Sync in IoT: Coordinated actions, accurate data analysis, and event logging in wireless IoT solutions often rely on devices having a shared time reference.
NTP's Role: Network Time Protocol (NTP) enables devices to synchronize their clocks against a reliable time source (NTP server), ensuring consistency across the network.
